Question

目前我有一个JSF - Primefaces Web应用程序，其中有多个（10）div容器，显示从Managed Bean获取的特定详细信息。容器将显示加载gif，直到获取信息。检索后，隐藏微调器div并显示信息。

参考下面的Snippet（显示1 Div）

<c:set value="#{cc.attrs.id}_panel" var="asyncPanelID"></c:set>
<h:panelGroup layout="block" class="content" id="#{cc.attrs.id}_panel" >
 <h:panelGroup layout="block" rendered="#{cc.attrs.map[asyncPanelID] ne ''}">
    <ui:include src="#{cc.attrs.contentFilePath}"/>
 </h:panelGroup>
 <h:panelGroup layout="block" rendered="#{cc.attrs.map[asyncPanelID] eq ''}" style="width:100%">
  <p:graphicImage url="/resources/images/Loading_Dots.gif" styleClass="loadingGif"/>
 </h:panelGroup>
</h:panelGroup>
<h:commandButton style="display:none" styleClass="#{asyncPanelID}">
    <f:setPropertyActionListener target="#{cc.attrs.map[asyncPanelID]}" value="true"></f:setPropertyActionListener>
    <p:ajax async="true" update="#{cc.attrs.id}_panel" ></p:ajax>
</h:commandButton>

页面工作正常一段时间，但随着负载的增加，它开始显示微调器，而不是响应。我正在使用Jboss EAP。

对于此类失败方案，Ajax响应如下

<partial-response><changes><update id="javax.faces.ViewState"><![CDATA[7655631808983688760:7124086963450351416]]</update></changes></partial-response>

成功回应

<partial-response><changes><update id="HeaderForm:quoteHeaderPanelTest:quoteHeaderPanelTest_panel"><![CDATA[<div id="HeaderForm:quoteHeaderPanelTest:quoteHeaderPanelTest_panel" class="content">
.
.
.
</update>
</changes>
</partial-response>

更新

删除async =“true”属性似乎有助于解决问题。但影响性能。还有其他方法吗？
